More fun with the My Photos screensaver

I have a small confession to make: I’ve been having a lot more fun than I anticipated with the img2txt MyPhotos screensaver I reluctantly cobbled together the other day.

So first things first: I’ll apologize for talking it down. I still won’t be putting any pictures of grandchildren on there though. :|

What’s the attraction? Call it a side effect of living through the 8-bit generation. I always find a certain measure of satisfaction in images that are somehow blocky and chunky, and not quite smooth or true-to-form.

Case in point:

A shameless plug for Ubuntu I suppose, but a good illustration of what “works.” Strong contrast between the image and the outlying areas, straightforward color arrangement and no awkward static that pollutes the final product.

On the other hand:

Obvious failure. Way too busy. Too much background noise, too many strong differences in color that get mushed about by the img2txt process. And no distinction between the focus and the environment.

And interestingly, many gradients fail for the same reason. Colors are translated unevenly at times, so an earthy green gradient, for example, will split into yellow and brown and green. Yuck.

The Internet loves Daft Punk, so …

This works quite well, partly because there’s no interference from outside the central image, and because the colors are strong. Interestingly enough though, lightning and fireworks — which you might infer work well, after seeing this — don’t.

For much the same reason, this works too.

Open the pod bay doors, Hal.

For an image that can dominate the effects of text conversion, here is an example.

I’m not a car person, but I sought this one out deliberately in hopes of getting something with a strong effect and a textured background. So yes, this was around No. 10 or so, on the list of attempts.

One more, and I’ll call it a day.

This one falls somewhere in the middle. It’s easy to see Tux and the trampoline on the hill, but the fun of the image is in the detail. So I suppose it’s only a half success.

For what it’s worth, the myphotos.sh script has burgeoned into this, for me.
